CD44 (redirected from CD44 molecule)
Also found in: Wikipedia
a type I transmembrane protein present on T cells, pre-B cells, monocytes, neutrophils, CNS white matter, fibroblasts, skeletal muscle, and medullary thymocytes; facilitates lymphocyte binding to endothelial venules and assists in adhesion.
CD44 A gene on chromosome 11q13 that encodes a cell surface glycoprotein involved in cell–cell interactions, cell adhesion and cell migration, and which is a receptor for hyaluronic acid. CD44 also interacts with other ligands—e.g., osteopontin, collagens and matrix metalloproteinases—and participates in a range of cellular functions including lymphocyte activation, recirculation and homing, haematopoiesis and tumour metastasis.
